兩岸關係研究在開放政策的導引下，自過去以共黨體制與理論研究，轉為更務實的經濟和文化研究，兩岸社會和人民透過頻繁交流瞭解彼此，是目前兩岸關係的重要發展，其中一項趨勢即是大陸年輕學生能在台灣停留，並在一段不算短的時間內深入一般民間生活，這些所謂的「陸生」在來台停留4個月以上的時間內，除了在學校上課，騎單車環島、搭「台灣好行」、搭台鐵、坐公車等等方式，在台灣城市和鄉野間體驗與感受，一部分人更在選舉造勢場合，和激動的選民一起喊凍蒜凍蒜。 根據Allport以來學者對於接觸相關研究文獻的瞭解，群際之間的研究必須考慮接觸的內涵、接觸的過程以及制約接觸的條件等對接觸效果的影響。傳統「接觸假說」認為類似文化背景之群體可透過深度交流接觸達到真正理解溝通，消除群際偏見與隔閡，達到族群融合。 本論文即以上述理論為基礎探討兩岸年輕學子交流的樣態及效，透過量化的問卷與深度訪談，探索這個族群接觸內涵與過程，理解到所謂的「接觸」並不能僅限於「接觸的頻率和時間長短」，也不能僅奠基在語言文化具類似性的基礎上，就達到「接觸假說」所預設的「消除類屬」(de-categorization)或進一步「融合類屬」(re-categorization)。因為族群之間各成員心中存在著「自我類屬」(self-categorization)，想要消融彼此的界線，必須先探索成員對自我類屬的定義，此外還須考慮接觸環境上制度面的制約，從制度面的設計增加群際成員的接觸頻率，才能進一步減少成員的「群際偏見」(intergroup bias)及增進「群際情感」(intergroup emotion)。 / In the leading of open policy, the mainstream of cross-strait studies has shifted from Socialism and Communism to Economy and Culture. At the tide of exchange, Chinese exchange students studying in Taiwan are the most propriate targets to learn about, less sensitive and having deep contact with Taiwan society. According to the related studies like Allport’s, scholars should take the content, process, and constrait of contact into consideration while studying the relations between nation groups. Traditional “contact assumption” assumes groups sharing similar culture background will reach mutually understand through exchange in depth, deliminate bias and barriers between groups. This study has examed the impact of the frequency and time length, the language and culture similarity on contact, knowing that those conditions above are not the only factors to de-categorization or further re-categorization. The members of each group have bared self-categorization in mind. Eliminating intergroup bias and enhance intergroup emotion would play an important part of breaking down the walls between groups. Besides, the goal of institutional design is to make the contact more intensive and to avoid the false contact. The less attractions offered by media to the Chinese exchange students, the less political socialization they will have. So the policy design should be delicate enough to allow those students to take the advantages of curriculums、professors, and schools to reach the goal of social contact between the young generations of cross-strait.

本研究是國內第一個以「警政負面新聞」為主題的研究，希望藉由第三人效果的認知假設，探討警政負面新聞的影響。除了探討警察人員對警政負面新聞是否存在所謂的第三人效果之外；並分別從人口變項、議題涉入感、社會距離、職業認同感等變項，探究對警政負面新聞的認知影響，同時也進一步就行為層面上的關係加以剖析。 本研究以服務於全國二十三縣市警察局之現職警察為目標，採用問卷調查法為主，回收並取得八百四十六份有效問卷。資料分析顯示，警政負面新聞對警察人員產生第一人和第三人的效果，受訪警察認為警政負面新聞對於自己的影響大於一般警察，即呈現了所謂的第一人效果；同時又普遍認為警政負面新聞對於一般民眾會產生更大的負面影響，呈現非常明顯的第三人效果。就社會距離而言，警政負面新聞對於一般警察和一般民眾的影響，會隨著與受訪者之間的距離增加而增加。這種社會距離的形成，肇因於不同團體之間的異質性和不確定感。 對於警政議題涉入感方面，研究證實受訪者對警政新聞議題涉入愈高者，普遍認為對自己、一般警察、一般民眾愈會造成負面影響。本研究同時發現警察的職業認同感維持在中度以上，結果顯示職業認同感可以正面預測「對自己的影響」、「對一般警察的影響」、「對一般民眾的影響」三者，即警察的職業認同感愈高，愈傾向認為警政負面新聞的負面影響愈大。受訪者認為警政負面新聞的影響愈大，愈傾向支持媒介限制行動。總的來說，警政負面新聞「對自己的影響」、「對一般警察的影響」、「對一般民眾的影響」等變項，均是預測支持警政機關採取媒介限制行為的顯著變項。 / This thesis is the first study in Taiwan focusing on “negative police news”, attempting to apply the third person effect theory to study the possible impact of negative news coverage of police. This research furthermore investigates several variables, including demographic variables, issue involvement, social distance, and professional identification, and their influence on the perception of negative police news. A relationship of exposure of negative news and support of media regulation is analyzed at the same time. A survey of 846 incumbent officers from twenty-three metropolitan police agencies in Taiwan was conducted. Results show that negative news coverage of police has both first and third person effects on police officers. Officers consider that effects of negative police news have stronger impact on themselves than on other officers. They generally consider that negative police news has more negative influence on the general public. From a viewpoint of social distance, an attitude formed through heterogeneity and uncertainty among different social groups, this study found that effects of exposure to negative police news upon perception of the effect on other officers were more limited than on the general public. From the aspect of issue involvement, the more the officers were involved in negative news issues, the more they consider negative police news has negative effects upon themselves, other officers and the general public. This study also concluded that the higher the professional identification a police officer held, the more she/he tended to consider that negative police news had a stronger impact. We also found that there was a tendency that police officers were more likely to support media regulation. Effects upon oneself, effects upon other police officers, and effects upon the general public of negative news coverage of police, were all variables significantly predicting the support of media regulation.
